can an opk detect pregnancy??

Okay i know this is kind of a stupid question but I didn't have any pregnancy test and I'm late and not sure what to do. So I was going to see if an Opk can detect pregnancy because that's all I have at the moment. I know when I ovulated and I've heard that if you take an opk and you are pregnant it will show up like a regular ovulation test. Anyway, that being said: I made my boyfriend pee on 3 and then I peed on 3 all mine show double lines and his doesn't😂 I know this is stupid but it's all I have rn
